Abstract
An actuator assembly for a vehicle brake system comprises a piston disposed in a bore, a reservoir, and a solenoid. A channel is in fluid communication between the bore and the reservoir, and the solenoid is disposed in the channel. The solenoid is movable between an open position and a closed position. In the closed position, the solenoid blocks fluid communication between the bore and the reservoir.
Claims20
An actuator assembly for a vehicle brake system, the actuator assembly comprising:
- a piston disposed in a bore;
- a reservoir;
- a channel in fluid communication between the bore and the reservoir;
- and
- a solenoid disposed in the channel, the solenoid being movable between an open position and a closed position, the solenoid in the closed position blocking fluid communication between the bore and the reservoir.
An actuator assembly for a vehicle brake-by-wire system, the actuator assembly comprising:
- a piston disposed in a bore;
- a reservoir;
- a channel in fluid communication between the bore and the reservoir;
- a solenoid disposed in the channel, the solenoid being movable between an open position and a closed position;
- and
- a controller for moving the solenoid to the closed position blocking fluid communication between the bore and the reservoir.
An actuator assembly for a vehicle brake-by-wire system, the actuator assembly comprising:
- a piston disposed in a bore;
- a reservoir;
- a channel in fluid communication between the bore and the reservoir;
- a solenoid disposed in the channel, the solenoid being movable between a normally open position and a closed position;
- and
- a controller for moving the solenoid to the closed position in response to a braking event, the solenoid in the closed position blocking fluid communication between the bore and the reservoir.
